* ARM gcc 4.8.2 and kernel builds @ 2014-11-13 3:31 Craig McQueen 2014-11-13 16:28 ` Otavio Salvador 0 siblings, 1 reply; 2+ messages in thread From: Craig McQueen @ 2014-11-13 3:31 UTC (permalink / raw) To: meta-freescale@yoctoproject.org I have been trying out kernel 3.18-rc4. I couldn't build it with the meta-freescale daisy SDK (which has gcc 4.8.2), because the kernel has blacklisted ARM gcc 4.8.0 through 4.8.2. The error message given says that it's because of a compiler bug which might lead to corrupted filesystems. Could this gcc bug also affect earlier kernels (either 2.6.35 in linux-imx, or 3.14 in linux-fslc), so is it worth updating gcc to 4.8.3 in meta-freescale daisy? -- Craig McQueen ^ permalink raw reply [flat|nested] 2+ messages in thread

Daisy has the fix backported[1] so it is safe for you to remove the check. 1. http://git.openembedded.org/openembedded-core/commit/?h=daisy&id=3004eb3b7ee5fd8dfe9c4e5749b4e125d0bd4b59 In either case I strongly advise to move to Dizzy now as it seems your project is at began. -- Otavio Salvador O.S.
